Abstract

The invention comprises a tensioner that is particularly useful in micro-V front end accessory belt drive systems used in automotive applications where minimum tensioner bulk combined with maximum balancing and minimum pivot bushing wear in order to achieve maximum pulley alignment over the expected life of the tensioner. The belt tensioner of the invention is of the type with a base. A pivot-arm is attached to a cylindrical member that supports the pivot-arm and rotates about a pivot secured to the base. At least one sleeve-type bushing is positioned on the pivot and includes a bearing surface that supports the cylindrical member. A pulley is attached to the pivot-arm for engaging the belt and receives a belt load that generates a belt force component that is transmitted to the cylindrical member (hub load) A torsion spring having one end connected to the base and another end interconnected to a damping means generates a damping force component acting in the opposite direction as the belt force component. The damping means is mounted substantially between the pivot-arm and the bushing along a plane parallel with the pivot.
